Explanation

Windows 32-bit operating systems are architecturally limited to addressing only 4GB of RAM (2^32 addressable memory locations), regardless of how much physical RAM is installed - so even a high-capacity HP Z workstation with 128GB of RAM will be capped at ~3.5GB usable when running a 32-bit OS. Option A is incorrect because having many DIMMs across channels doesn't inherently limit capacity - it's how workstation platforms are designed to scale. Option C is wrong because 64-bit Windows supports very large memory amounts (up to several TB), making it the correct OS choice for workstations. Option D is incorrect because while mixing DIMM sizes can affect performance or require specific slot configurations, it doesn't fundamentally cap total memory capacity.

Memory tip: Think "32-bit = 32 fingers to count with" - you run out of fingers (addressable space) very quickly, no matter how big the workstation is.
